98 Camry oil pump replacement? Sensor?

OK I have a major leak from the right side of my car and have come to a conclusion base apon where it is leaking from that it is the oil pump that I will have to replace. My question is anyone who has done this before can I just get the oil pump without the sensor and use my sensor or will I have to buy the pump with the sensor? ( car is a 98 camry le 4 cylinder)
